As if a concert featuring some of the most legendary, if not washed-up, former boybands could get any better...the Tacoma Dome announced that Glee's Matthew Morrison will also make a guest appearance at the show.

The rockers (can we call them that?) will take the stage July 8, and tickets are still on sale for $31.50-$91.50. But really, can we put a price tag on a show that brings together Marky Mark's brother and the boys who "Want it that way?" Didn't think so.

Catch a preview of the concert when the boys perform on the TODAY Show June 3.
